1) a.swc - Library project - which has set of classes that is being shared amont mainApp and module1.

2) a.swc has set of custom libraries as SWC included as merged into code for e.g b.swc,c.swc.

so a.swc file has

set of classes that i had written

b.swc(merged into code) in same SWC file.

c.swc(merged into code) in same SWC file

When i add a.swc inside my Mainapp.mxml as merged into code or RSL then i am able to access all the classes that exist in a.swc file but not that is in b.swc and c.swc file . Same is case with the modules.
